The rapidly decreasing water levels in Lake Mead, the biggest reservoir in the United States, have lately grabbed global news.
Hoover Dam on the Colorado River creates a reservoir spanning Nevada and Arizona.
Which in turn delivers power to tens of thousands of local residents.
It has been rapidly approaching dead pool level, which might have disastrous effects, because to the current drought in the western United States.
But for the first time in three years, its water levels are rising.
The lake's water level dropped to 1,040.71 feet on July 27th, the lowest level since the 1930s, shortly after its creation.
